DeKALB – Jim Briscoe said families and students should curb excitement about a potential snow day Tuesday despite forecasts predicting a half foot of snowfall starting early in the morning.

Briscoe, superintendent of DeKalb School District 428, said the most recent snowstorms have fallen short of predictions and Tuesday's snowfall could be less than expected. He said he would make a final decision on any school closures between 5:15 a.m. and 5:30 a.m.

"It's really hard to predict ... we need to wait to see if the weather actually occurs," Briscoe said. "It could be sunny and 35 degrees."
